Mario Legacy 0.1 is one of those weird, unofficial SNES romhacks that feels like stumbling into an alternate universe where someone remixed classic Mario levels with their own bizarre twists. You’ve got familiar sprites and mechanics, but the level design throws curveballs—expect sudden bottomless pits where there shouldn’t be, enemies stacked in ridiculous formations, and power-ups hidden in places that make zero sense.

It’s janky in that charming, early-fangame way—like the creator had big ideas but ran out of patience halfway through. Some jumps feel unfairly tight, and there’s a solid chance you’ll lose a life to some off-screen enemy you never saw coming. But there’s something weirdly addictive about pushing through the jank to see what nonsense the next level holds.

If you’re into obscure Mario hacks for the novelty alone, this one’s a curiosity worth booting up—just don’t expect polished gameplay.
